Chattanooga Hot Packs
Chattanooga Hydrocollator® Packs - HotPac Moist Heat & Steam Packs
Bought several of these 24 years ago when I started out. They lasted 20 years. Bought replacements 4 years ago and the stitching gives out and the packs actually leaked on my patient. Avoid a malpractice suit and buy a different brand.
